jib-gradle-plugin v3.3.0

Major Changes

• Included imagePushed field to image metadata json output file which provides information on whether an image was pushed by Jib. Note that the output file is build/jib-image.json by default or configurable with jib.outputPaths.imageJson. (#3641)
• Added lazy evaluation for jib.extraDirectories parameters using Gradle Property and Provider. (#3737)
• Added better error messaging when environment map in container.environment contains null values (#3672).
• Added support for OCI image index manifests (#3715).
• Added support for base image layer compressed with zstd (#3717).
• Upgraded slf4j-api to 2.0.0 (#3735).
• Upgraded nullaway to 0.9.9 (#3720)
• Jib now only checks for file existence instead of running the executable passed into dockerClient.executable for the purpose of verifying if docker is installed correctly. Users are responsible for ensuring that the docker executable specified through this property is valid and has the correct permissions (#3744).
• Jib now throws an exception when the base image doesn't support target platforms during multi-platform build (#3707).
